Abstract

Beschrieben wird ein mehrlagiger Luftfilter umfassend eine Filterschicht, die rohgasseitig von einer Vorfilterschicht überdeckt ist, die einen trocken gelegten elektrostatisch wirksamen Vliesstoff, vorzugsweise einen Stapelfaser-Vliesstoff, aufweist, dessen Flächengewicht 10 bis 100 g/m2 beträgt.
Der Filter lässt sich insbesondere als Staubsaugerbeutel einsetzen.
